摘要： The goal of this invention is to produce phenol of high purity by conversion of impurities that are present in the starting phenol, which is produced by the decomposition of cumyl hydroperoxide. The indicated goal is achieved by purifying the phenol containing admixtures of aliphatic and aromatic carbonyl compounds with an aluminum zirconium catalyst. The catalyst comprises a mixture of aluminum and zirconium oxides and sulfates and has a total content of aluminum and zirconium sulfate of from 5 to 15% by mass (calculated on the basis of SO4 ions) and the catalyst has a total content of aluminum and oxide and sulfate of 5 - 30% mass (calculated on the basis of aluminum oxide). The catalyst can be prepared by treating zirconium hydroxide twice using sulfuric acid in both a sulfation and a peptization step, and using aluminum oxide that consists of a mixture of boehmite and pseudoboehmite in a mass ratio of from 1:3 to 3:1.
